Abstract

La présente invention concerne un ensemble de codeur magnétique rotatif qui a un aimant d'excitation rotatif à roue libre qui excite une région de capteur de champ magnétique d'une puce de codeur lorsqu'une interaction magnétique entre l'aimant d'excitation et l'arbre du codeur rotatif amène l'aimant d'excitation à tourner. Dans un mode de réalisation, un aimant d'entraînement porté par l'arbre se couple magnétiquement avec l'aimant d'excitation du fait que le milieu entre eux a une faible perméabilité magnétique permettant une rotation sensiblement à l'unisson avec l'arbre. L'aimant d'excitation est disposé dans une poche de retenue embarquée qui localise précisément l'aimant par rapport à la région de capteur de la puce du codeur. Dans un mode de réalisation préféré, la poche de retenue de l'aimant d'excitation est disposée à bord de la puce du codeur, comme, par exemple, en étant formée comme une partie du corps de boîtier de la puce qui peut être formé solidairement ou comme une partie d'un module qui peut être monté sur la puce.
